¹¹ The precise number of physicians who were not employed by the GMS and who had only private practices is uncertain but apparently small. Late nineteenth-century Demerara magistrate Henry Kirke, e.g., claimed that there were about six private practitioners in the late 1890s; John Anderson, in his account of filariasis in British Guiana, noted that there were “several” private practitioners in Georgetown in the 1920s.
